Vickers Micro-Hardness Lab

Objective

The new UHL VHMT not only has an exceptional new design, it makes micro hardness testing more convenient for the user than any other instrument:

• 12 steps of test force yield more than the range required by ASTM E-384/EN ISO 6507/EN ISO 4545.
• Motorized selection of test force offers full control via touch panel display there is no mechanical dialling knob necessary.
• Selectable approach velocity prevents bouncing effects on specific materials.
• Focus finder helps to quickly determine the focal plane especially in case of highly polished samples.
• The VMHT MOT offers a motorized turret and a touch panel display for more comprehensive information and interaction.
• The VMHT MOT offers a motorized turret and a touch panel display for more comprehensive information and interaction.
• Due to the outstanding optics it can be used as a simple bright field metal microscope.

Utility and Working Principle

The indentation "Micro hardness" derives from the field of hardness determination by means of an indenter entering the material to be tested with a specific load and dwell time. After removing the indenter, the produced imprint is measured and the "hardness number" calculated.
